can i close electrum during a transaction?

Hackers have launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials.

At the time of the madness, malicious ElectrumX servers accounted for as much as 71% of the total, and the show did not fully count that hundreds of bitcoins had been stolen in this phishing attack over the past year or so.

Wallet history can be obtained from a central server, such as an Electrum server, but each address uses a new Tor circuit. A closely related idea is to connect the Electrum servers in the onion routing network together.
